Methodology:
Sourced from the OpenRouter model catalog, refreshed daily — the same data behind the
AI Model Market Report.
"Open-weight" means OpenRouter lists a Hugging Face id for the model, not a judgement about its license text.
Region is a best-effort match on the model's provider org — recognised orgs are grouped into US, EU, or China; anything unrecognised is shown as "Other" rather than guessed.
"Tier" uses the same input-price bands as the
AI Price Comparison page — Budget under $0.50 per 1M input tokens, Mid $0.50–$3, Premium $3 and above.
